Dex mode mouse only appears on phone not the external display

Are you using a USB C - USB C cable? Are you using an external mouse? Have you tried wiping the cache partition?

@Rydah Do you have any ideas on why the mouse pointer is not appearing?

@SamsungGill 

I can't reply directly to your post as it errors out.

I'm using the dexpad docking station connected via HDMI cable to an external monitor and via USB to a wireless mouse.  The problem also occurs while using the phone as a touchpad which clearly indicates its a driver problem and not a peripheral problem.  Despite that I've attempted to swap out the mouse with the same result.

@Sumwun  Sorry about the reply issue, there's some odd things going on with reply in the Community right now. A ticket has been put in for it.

Try wiping the cache partition on the phone. I just tried the same setup with a wired mouse and was able to see the cursor with and without the mouse connected.

Ya I cleared all that out, cache and the settings, reverted back to default.  Only thing I haven't done is a complete wipe on the phone which I'm not inclined to do unless I know for sure this is a one time thing because of the security software I have for work.

It might be worth noting, or this might be an entirely unrealted additional Dex mode problem.

When I connected to my PC at home in virtual dex mode through the USB to USB-C cable, I couldn't breifly use the menu to access the apps.  After a reboot it seemed to work HOWEVER, virtual mode only seems to work for a short time before it freezes and locks up my phone with severe distortion on the screen, I have to hard reboot the device to get it unfrozen.  However I don't want to dwell on that at the moment, I'm more concerned with the mouse not working.

That's kind of a significant note. I use the virtual DeX regularly with no real issues aside from when I'm doing something resource intensive.

I know you said that the software was up to date but I just want to verify before you reset the phone.

Who is your carrier? Please provide the current Baseband version.

@SamsungGill 

AT&T is the carrier, however this is an unlocked device

Baseband is N975U1UEU1ASH4

[SamsungGill]

Thank you, it's up to date so the next step would be a factory reset. Please back up your accounts before hand.

Just another confirmation, I tried the DeX station with a wireless mouse and was able to see the cursor.
